Leakage, sound and light alarm prompting；During No leakage, alarm free prompting continues normal work；
Embodiment 2：In the case where vehicle power supply is without electricity, using standby power supply module, external communication module power supply is closed,
Using time sharing mode, for reducing power consumption, lengthen working hours：
A. 5:00~21:00, every 10 minutes, start once, 21:00~5:00, every 30 minutes, start once；Every time
2 minutes working times, for starting main frame temporarily, external communication module is closed, main frame backlight is closed, is leaked and passed by host computer control
Sensor, starts leak sensor, judges the hydrogen gas leakage state of vehicle.
B. as do not detected hydrogen fuel leakage, after 2 minute working time is reached, main frame can enter resting state,
Wait next start-up course.
C. hydrogen gas leakage is such as detected, then no matter in any time, BMS battery management systems start once for every 5 minutes
Main frame, 1 minute every time, detects whether there is hydrogen gas leakage, untill hydrogen gas leakage concentration exceedes alarming value.
D. detect after the hydrogen gas leakage alarm transfinited, main frame does not restart leak sensor, BMS battery management system works
As state be changed to only powered to warning system, Host Shutdown is externally communicated, and also stops powering to leak sensor, only allow alarm be
System work, and time-sharing work, for reducing power consumption, extend time of fire alarming；Sound and light alarm part, using alarm in every 2 seconds once, often
Secondary 0.5 second mode, during alarm, lights display screen, the information such as position and the concentration of hydrogen gas leakage alarm is pointed out, until correlation technique
Personnel have been handled after leakage situation, into normal power-off monitoring state.
Embodiment 3：In the case where automobile power source has electricity again, main frame normal work such as has been detected by hydrogen gas leakage
Alarm condition, then continue to alarm, untill person skilled processing leakage situation；In the feelings alarmed in the absence of hydrogen gas leakage
